What is the inverse function of d(x ) = -2x - 6?

PtichkaEL [24]

Answer:

$-\frac{x}{2} - 3$

Explanation:

d(x) = -2x - 6

to find the inverse of a function, you need to follow these steps:

1. set d(x) = y

2. interchange the variables, so y becomes x and x becomes y

3. solve the equation for y

<u>step 1:</u> set d(x) = y

y = -2x -6

<u>step 2:</u> interchanging the variables

y = -2x - 6 turns into x = -2y - 6

<u>step 3:</u> solving for y

x = -2y - 6 < add 6 to both sides to get rid of it on the right

x + 6 = -2y < divide both sides by -2 to get y alone

x + 6 / -2 = $-\frac{x}{2} - 3$

-2y / -2 = y

$-\frac{x}{2} - 3$ = y

so the inverse of the function is $-\frac{x}{2} - 3$

Create a class Str that subclasses str. Add a method to the subclass that checks if the string does not start with a given strin

Stolb23 [73]

Answer:

#include <iostream>

using namespace std;

class Str{ ///baseclass

public :

string super_str;

string getStr()

{

return super_str;

}

void setStr(string String)

{

super_str=String;

}

};

class str : public Str{ //inheriting Str publicly

public :

string sub_str;

string getstr()

{

return sub_str;

}

void setstr(string String)

{

sub_str=String;

}

bool notstartswith()

{

int n=sub_str.length(); //to find length of substr

bool flag=false;

for(int i=0;i<n;i++) //Loop to check beginning of Str

{

if(super_str[i]!=sub_str[i])

{

flag=true;

break;

}

return flag;

}

};

int main()

{

str s; //object of subclass

s.setStr("Helloworld");

s.setstr("Hey");

if(s.notstartswith()==1) //checking if str is substring of Str

cout<<"Str does not start with str";

else

cout<<"Str starts with str";

return 0;

}

OUTPUT :

Str does not start with str

Explanation:

Above program is implemented the way as mentioned. for loop is being used to check the beginning of the str starts with substring or not.
